European Chemicals Agency (ECHA) unveiled a restriction proposal on per- and polyfluoroalkyl substance (PFAS) on February 7, 2023. PFASs refer to substances that contain at least one fully fluorinated methyl (CF3-) or methylene (-CF2-) carbon atom (without any H/Cl/Br/I attached to it). They are persistent substances, also named “forever chemicals”, which will lead to irreversible environmental exposure and accumulation.
